My invention relates to railway rolling stock and consists in a novellocomotive frame-and air reservoir construction. V

The main object of my invention is to con-. struct an air reservoiradapted to be, placed longitudinally of the locomotive between andconnected to the sideframes thereof, such" reservoir, and itsconnections to the side frames being adapted to form a substantial.reinforcement for'the frames and tov share the longitudinal forcesimposed on said. frames. The reservoir may beformed: of aplurality ofmembers each of arcuate cross section and flanged to engage the adjacentmember ormembe'rs; l v

In. the construction shown in and 3,'the,reservoircomprises two mainportions 1 and 2 extending longitudinally of the.

locomotive. The lower or body portion 1 re-- sembles a trough in outlineand the upper portlon 2 resembles an inverted trough fitting overportion ,1. Preferably, each of these portions comprises a casting whichcan be made of any desired width, length and thickness to capacity.

1 The lower portion 1: is provided with integral brackets 3 and A for.-attachment to the locomotive side'frames 5 Each bracket 4 Figures 1, 2

provide required strength and inoludes'a'downward extension 6 which mayi be bolted or leg7.- i v Suitable vertical ribs 8 extend transverselyand exteriorly of the-reservoir body be tween brackets 3 and/1,reinforcingv the same 7 and the body of the reservoirportion and alsoextending between and reinforcing horizontal flanges 9 extending aroundthe upper to be joined with corresponding flanges 10 formed'on the loweredges of the upper por- The lower reservoir portion l is preferably 1provided with integral expansion plate brackets 12 which extend-upwardlybeyond the connecting flanges 9 and 10 and the upper reservoir portionis provided with integral brackets 13' for holding radiating pipes 14.v. V

A relativelydeep transverse web 15 braces the vertical brackets 6throughout their depth and serves as abrace forthecor'respondingpedestals. This web is provided with a horizontal flange16 at its lower edge the section. V v

-.The two reservoir portions 1 andg2, may be united by any suitablemeans, such as and with suitable openings 17 for lightening otherwisesecured to the pedestal V bolting, riveting or welding and, whenc'ompletely assembled with the locomotive frames, constitute a;substantial part ofthe framing thereby greatly reinforcing the sidesand, if desired, making it possible to use side frames of less weightthan would be practical with the ordinary framing with the reservoirmounted on the exterior of the boiler shell.

The structure is adapted. to transmit forces longitudinally, verticallyor transversely and by forming the expansion sheet brackets 12,

radiating pipe brackets 13, brake hanger brackets 18 and connectingmembers 6 integral with the reservoir a large amount of fitting andassembling work is eliminated which is usually required for theapplication of these and similar parts to the locomotive frame.

In the structure illustrated in Figure 4, the upper portion 19 of thereservoir has the expansion plate brackets 20 integral therewith andextending around the exterior of the reservoir section, as indicated at21, to form a substantial reinforcement of the body of the reservoir.The brake hanger lugs 22 are integral with the lower reservoir section23 as in the preferred construction.

In the construction shown in Figure 5-, the brake hanger lug 24 and theexpansion plate bracket 25 are both formed integrally with the uppersection 26 of the reservoir and the lower section 27 terminates with thebracket- 28 by which it is secured to the side frames 29.

In the structure illustrated in Figures 6, 7 and 8, the reservoir issplit vertically along its center line and the two sections 30 and 31are secured to each other in any suitable manner, for example, by theprovision of riveted flanges, as indicated at 32. Each section includessuitable brackets 33 for at tachment to the frame 34 and also includesone or more transverse braces 35 for connection to pedestal jaws 36 ofthe frame. Similarly, each section includes pipe brackets 37, expansionplate brackets 38, and brake hanger brackets 39.

In Figures 9, 10 and 11, the complete reservoir is embodied in a singlestructure 40 which is applied as a unit to the side frame 41 bv means ofthe brackets 42, certain of which bi'ackets also include the brakehanger brackets 43 and expansion plate brackets 44. The pipe brackets 45are integral with the reservoir and the deep cross bar 46 is alsointegral with the reservoir and is attached to the'frame pedestals 47 asin the other struc tures previously described. If a reservoir of thistype is formed by casting, as is my preferred construction, formation ofthe body will require a cylindrical core and, to facilitate the moldingand casting operation, the shell of the reservoir will be provided witha series of openings 48 which are closed upon the completion of thedevice by welding suitable cover plates 49 to the body of the reservoir.

modification of my invention in which the lower portion 50 of thereservoir is formed integrally with the side frames 51 of thelocomotive, suitable transverse members 52 corresponding generally tothe brackets 3 and 4 of the preferred structure but merging with thesides of the locomotive frame. The brake hanger brackets 53 and theexpansion plate brackets 54 are integral with the sides of the frame.Preferably, but not necessarily, the sides of the reservoir body 50 areconnected at intervals by suitable braces 55.

The upper portion 56 of the reservoir is 61 provided on the mainstructure. Prefer-.

ably, each of the reservoir portions is suitably braced by braces 62 and63, respectively, brace 62 being of deeper section to adequately bracethe frame transversely of its length.

The modification illustrated in Figure 16 includes a main portion 64,the sides of which extend to a higher level than indicated in Figures 14and 15 and the reservoir body is completed by the addition of a plainarcuate section 65 which may comprise a sheet of boiler plate, ifdesired. This element 65 overlaps the edge portions of member 64 and issecured thereto by screws 66 and by welding as indicated at W. Byproviding a suitable man hole in the reservoir, rivets may besubstituted for screws 66. In all the forms of my invention, the generalobjects stated at the beginning of the specification are attained to asubstantial degree. The material usually required for separatelyfabricating and mounting the ordinary reservoir tanks may be used toform a part of and strengthen the locomotive underframe and the spacetaken up on the exterior of the locomotive boiler by the usual reservoirmay be used for other purposes. The center of gravity of the locomotivestructure is lowered by carrying the air reservoirs between the sides ofthe framing instead of at a substantial height above the same.

In connection with the present application, I refer to my copendingapplication Serial No. 407,199, filed of even date, some features ofwhich are common to the present application.
